It's intriguing that Sanchez would prefer to continue his development under Chip Kelly over joining a team looking for a starter. It tells us the quarterback isn't thrilled with the concept of rejoining play-caller Brian Schottenheimer in St. Louis.

Schotty's bland paint-by-numbers scheme has the opposite effect on quarterbacks compared with Kelly's wide-open, up-tempo attack. Like Nick Foles, Sanchez has seen his numbers skyrocket in Philly, generating a heady passer rating of 112.5 and throwing for 9.1 yards per attempt in August. Sanchez never topped 6.7 yards per throw under Schottenheimer in New York.

Sanchez has transitioned well to the Eagles and seen his perceived value shoot upward in just three preseason tilts. Set to become a free agent in March, it makes sense he'd want to stick around and see how high he can climb by year's end.
